On Wednesday, the impossible dream, the flight of fancy, the ridiculous notion became reality: Floyd Mayweather, owner of all sporting pay-per-view records of note, will exit a two-year retirement for the August 26 boxing match against Conor McGregor, the brightest star mixed martial arts has ever seen.

McGregor is the highest-paid Ultimate Fighting Championship athlete ever, but the leap he is about to make is an extraordinary one. He says he’ll go from his comparatively low estimated paydays to over $100 million in one night.

And then, according to UFC President Dana White, he’ll come back to the UFC for a lightweight title defense in December, where he will presumably go back to making $3 million guaranteed for his fights. From $100 million to $3 million, for the same amount of work.

Sure he will.

One hundred million dollars. McGregor is already a winner, even in the event Mayweather defensive-boxes his way to a win.

I’m not sure if McGregor has anything left to prove. The disproportionally large number of naysayers grows exponentially before every one of his fights. He beat Chad Mendez. He beat Jose Aldo. He beat Nate Diaz in UFC 202 (after initially losing to Diaz in UFC 196). He beat Eddie Alvarez.
